Ries 3). An additional batch of 12 plants was made use of to study the effect of mefenpyr-diethyl on individual plant sensitivity to iodosulfuron + mesosulfuron (experiment series 2) and on the expression of Lolium sp. NTSR marker genes (experiment series three). Plants had been grown in individual 2 L-pots inside a glasshouse at 22 C/18 C day/night with 14-h photoperiod. In the sixteen-tiller stage, they have been subjected to vegetative propagation: all person tillers had been separated and transplanted into person pots. For every plant, this yielded 16 clones (genetic replicates) at the 3-4-leaf development stage. The distribution of the 16 clones per plant over the two series of experiments is summarized in Figure 1. The batches of cloned plants intended for cloquintocet-mexyl impact investigation were sprayed based on 5 modalities with each compound applied in the French field price (Figure 1). Modalities integrated water-sprayed (W), Actirob applied at 1 L ha-1 (A), cloquintocet-mexyl applied at 18.75 g ha-1 (C), pyroxsulam applied at 18.75 g ha-1 with Actirob at 1 L ha-1 (AP) and pyroxsulam and cloquintocet-mexyl applied at 18.75 g ha-1 with Actirob at 1 L ha-1 (APC). The water-dispersible granule formulation of the commercial herbicide Abak was made use of for modalities APC, AP, and C so that no bias because of the herbicide formulation was introduced within the experiment. Four clones per plant had been included in modalities UT, AP, and APC, and two clones per plant within the other two modalities. Two clones per plant and per modality had been intended for RNA extraction (clones for experiment series 3, Figure 1). The remaining two clones in each and every of modalities W, AP, and APC were utilized toFIGURE 1 | Distribution of your 16 clones per rye-grass plant studied among the experimental modalities in the two series of spraying experiments utilised to produce plant material to investigate safener impact on individual plant phenotype (experiment series 2) and on NTSR marker gene expression (experiment series 3).Frontiers in Plant Science | frontiersin.orgAugust 2017 | Volume 8 | ArticleDuhoux et al.Safeners Lower Herbicide Sensitivity in Rye-Grassdetect shifts in herbicide sensitivity of individual plants triggered by the presence on the safener by comparing the phenotypes of clones sprayed using the pyroxsulam alone (AP) or in association with cloquintocet-mexyl (APC) (clones for experiment series two, Figure 1). The batches of cloned plants intended for mefenpyr-diethyl effect investigation were also sprayed as outlined by 5 modalities with every single compound applied in the French field price (Figure 1).

As for the preceding plant batches, four clones per plant had been included in modalities AE, AEIM, and AEIMM and two clones per plant in the other two modalities. Two clones per plant and per modality were intended for RNA extraction (clones for experiment series 3, Figure 1). The remaining two clones in each of modalities AE, AEIM, and AEIMM have been made use of to detect shifts in herbicide sensitivity of individual plant.
